9. The gravitational waves and light waves arrived within seconds of each other, suggesting they may travel at the same speed and confirming a prediction of Albert Einstein. The difference in detection time is likely a reflection of what happens during the explosion process.
引力波和光波到达地球的时间相差只有几秒钟,这意味着两者传播速度一样,证实了爱因斯坦的猜想。探测时间的差异很可能反映出合并过程中发生了什么。
10. Only gravitational wave observatories can directly detect unexploded binary neutron stars outside of our local galactic neighborhood, or directly observe the stars pre-collison, albeit only briefly before impact.
只有引力波天文台能够探测到银河系外未爆炸的双中子星,或者直接观测合并前的双中子星,不过只是在合并或爆炸前很短的时间内。
